Are you including yourself in "most"?

No .

I expect Joel might have to fill in at centre quite a bit this year! He has got the right sort of skills for the role and could become a very dangerous player in the position. It makes sense for the club to at least see what he is capable of. If, even if some think it's unlikely, he is a big success there then it gives more options. If he shows that he's a capable stand-in then that's good too. There's no harm in playing him centre against Salford. Perhaps there'd be no harm in him playing centre permanently either. It makes sense for the club to test him in a position that he could be successful in.

im with that.........can do everything a centre needs to do.....except pass.
he can offload, but its not the same as drawing in players and passing to the winger.

With coaching and experience Joel has the size, speed, power and presence to be a cracking centre.
Sam is unfortunately wasted at full back.
